I have seen this topic many times on this board and it seems that when every thing is set up correctly and this test is still failing that the answer seems to be for some cache to be reset.  I am trying to figure out if I am having a genuine mistake or if I fall into the latter category.  As far as I can tell based on the digs below I can get correct answers on ipv6 from all the proper places.  Am I missing what step 3 of the guru test requires ?

Thanks
